Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner used in ordinary households.

[0002]

2. Description of the Related Art In a conventional vacuum cleaner, an auxiliary nozzle 22 such as a gap nozzle or a tana nozzle is housed in a cleaner body 21 as shown in FIG. Further, as disclosed in Japanese Patent Publication No. 5-50933, it is attached to a holder attached to an extension tube, and as described in Japanese Patent Application Laid-Open No. 9-47393, an opening member provided at a locking portion provided at a hand handle is provided at a skimmer nozzle. One that engages a stop portion, and another that attaches an auxiliary nozzle 22 to a protruding portion 24 of a cover member provided at a distal end portion of a hand handle 23 by using a holder 25 as shown in FIG. . These conventional devices are used by detaching the auxiliary nozzle 22 such as a skimmer nozzle or a tana nozzle from the tip of the main body of the vacuum cleaner or the extension tube and from the hand handle and attaching it to the hand handle or the extension tube.

[0003]

However, in this prior art, when the cleaning is performed by replacing the floor nozzle with a clearance nozzle or a tana nozzle according to the cleaning place, the main body 2 is not used.
1 to accommodate the auxiliary nozzle 22, 5-50
No. 933 is difficult to use because the auxiliary nozzle is difficult to remove. In addition, in Japanese Patent Application Laid-Open No. 9-47393, it is difficult to set an opening locking portion for a tana nozzle using a bristle brush because an opening locking portion is provided in an auxiliary nozzle. Has issues. When the auxiliary nozzle 22 is attached to the projection 24 of the cover member provided at the tip of the handle 23 using the holder 25, the auxiliary nozzle 22 moves back and forth during use and falls off. Since the auxiliary nozzle 22 is protruded and held larger than the handle 23 at hand, there is a problem that the auxiliary nozzle 22 easily hits the body during operation and falls off.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has as its object to provide a vacuum cleaner having a simple structure and a good operability in which a skimmer nozzle, a tana nozzle and the like can be easily attached and detached. I have.

[0005]

In order to achieve the above object, according to the present invention, there is provided a holding device having a locking portion integrally formed at a lower portion of a curved portion of a hand handle and having a fitting portion and a fitting portion. In addition to locking the stopper, a tana nozzle, a skimmer nozzle, and the like are engaged with the fitting portion of the holder and detachably mounted to facilitate replacement of the nozzle.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION
